The error message is only occuring before the first contact is  
uploaded. While this looks like a bug, it shouldn't affect your sync.  
It does look like a bug though. What is happening is that the initial  
state is not being stored, probably because it only stores the state  
after a change - and you have no contacts on the server being sent to  
the device.

Your log shows a successful PING request and handling at the end. You  
can test this by entering a contact, or changing the existing contact,  
from within Horde. You should see a fairly quick change sent to the  
device. Horde has no control over when the device decides to send up  
device changes. It could be that it waits until the currently running  
ping is finished.

The only thing I can think of is that because a few PING requests  
resulted in requests for resyncs, the client might have throttled the  
sync. See if editing a contact on the server results in a successful  
sync back to the device and, if so, if that triggers the client to  
start sending changes again.

Either way I'll look into fixing the initial state-storing bug if it's  
not already fixed in Git.
